2012-11-13smbd: Remove NT4 compatability handling in posix -> NT ACL conversionAndrew Bartlett2-20/+0
NT4 is long dead, and we should not change which ACL we return based on what we think the client is. The reason we should not do this, is that if we are using vfs_acl_xattr then the hash will break if we do. Additionally, it would require that the python VFS interface set the global remote_arch to fake up being a modern client. This instead seems cleaner and removes untested code (the tests are updated to then handle the results of the modern codepath). The supporting 'acl compatability' parameter is also removed.

2012-10-30ldb: Add ldbdump, based on tdbdumpAndrew Bartlett2-0/+223
This uses a tdb_traverse or (more usefully) the tdb_rescue API, like tdbdump. The difference here is that it uses ldb helper functions to further eliminate faulty records, which avoids creating duplicates in the output. (The duplicates come from parts of records that are left in blank space in the db, which tdb_rescue finds, but which are not actually a full record).

2012-10-06tdb: Make tdb robust against improper CLEAR_IF_FIRST restartVolker Lendecke1-4/+28
When winbind is restarted, there is a potential crash in tdb. Following situation: We are in a cluster with ctdb. A winbind child hangs in a request to the DC. Cluster monitoring decides the node has a problem. Cluster monitoring decides to kill ctdbd. winbind child still hangs in a RPC request. winbind parent figures that ctdb is dead and immediately commits suicide. winbind parent is restarted by cluster management, overwriting gencache.tdb with CLEAR_IF_FIRST. The CLEAR_IF_FIRST logic as implemented now will not see that a child still has the tdb open, only the parent holds the ACTIVE_LOCK due to performance reasons. During the CLEAR_IF_FIRST logic is done, there is a very small window where we ftruncate(tfd, 0) the file and re-write a proper header without a lock. When during this small window the winbind child comes back, wanting to store something into gencache.tdb, that winbind child will crash with a SIGBUS. Sounds unlikely?

2012-10-06tdb: Make robust against shrinking tdbsRusty Russell1-12/+20
When probing for a size change (eg. just before tdb_expand, tdb_check, tdb_rescue) we call tdb_oob(tdb, tdb->map_size, 1, 1). Unfortunately this does nothing if the tdb has actually shrunk, which as Volker demonstrated, can actually happen if a "longlived" parent crashes. So move the map/update size/remap before the limit check. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

2012-10-05Add memory limiting capability to tallocSimo Sorce5-40/+327
By calling talloc_set_memlimit() we can now set a max memory limit for a whole talloc hierarchy. ANy attempt to allocate memory beyond the max allowed for the whole hierarchy wil cause an allocation failure. Stealing memory correctly accounts for used memory in the old and the new hierarchy but exceeding the memory limit in the new parent will not cause a failure.
